Trei D
The world of 3D printing has seen remarkable progress in recent years, with different manufacturers competing to produce high-performance models. Among them, FLSUN has become a prominent player, known for its delta motion 3D printers. In this article, we explore the FLSUN S1, their announced “flagship”, and delve into features, and specifications.
Ultra-High Speed for 3D printing
FLSUN built the S1 for speed. It can reach print speeds of up to 1,200 mm/s thanks to closed loop stepper motors and a maximum acceleration of 40,000 mm2/s adding a hotend that is capable of reaching a flow of 110 mm/s. This makes it one of the fastest FDM printers on the market. The high temperatures supported by the all-metal hotend, which is equipped with an 80W ceramic heating element and can reach up to 350°C, also facilitate faster printing with a diverse range of materials.
Inovations?
From information from FLSUN, the S1 will be equipped with several innovations such as:
- CPAP-type turbo fan capable of 40,000 RPM and taking only one second to cool a single layer (I don’t really see where the innovation is, as there are already 3D printers that use CPAP-type fans, such as VzBot)
- Closed loop stepper motors (I’m not aware of any 3D printers on the market that come stock with this yet, apart off Magneto X )
- Flsun OS – it looks like the new printer will have a proprietary operating system, compared to the FLSUN V400, which runs on Klipper. We still don’t know if this OS is based on klipper, or if it will be something different.
More and more AI
With the meteoric advance of artificial intelligence, it looks like we’ll see more and more of this technology implemented in 3D printers. The FLSUN S1 will have an AI assist system, Microtac Radar, it will take care of calibrating the accuracy of movements, first layer scanning, hotend flow calibration and auto bed leveling using a Lidar scanner built into the hotend, probably something similar to Bambu Lab’s printers. The S1 is also equipped with a 1920×1080 resolution camera for real-time monitoring, timelapse and print problem detection using AI.
Friendly with begginers?
The FLSUN S1 will be equipped with a filament dryer capable of monitoring temperature, humidity and the amount remaining. The printer’s generous 320mm bed has two heating zones: the inner circle up to 220mm and the outer circle between 220mm and 320mm, and can reach 120°C. It is mentioned on the manufacturer’s page that the printer will be able to compensate for vibration, but it is odd that the Speeder Pad G sensor ADXL345 Vibration Compensation is included in the kit for sale. I assume that the printer will be factory calibrated, with no option for users to calibrate the vibration compensation.
Conclusion and Price
FLSUN seems to be aiming very high with the promised capabilities and reliability of the FLSUN S1 3D printer but the $1499 price tag puts it in a rather poor position compared to the X1-Carbon which now on Black Friday is at a better price, and comes equipped with AMS. In specs and print volume it is close to the Creality K1 Max, but the latter costs $719. It remains to be seen whether the S1’s combination of state-of-the-art hardware and software could set a new speed record for FDM printing.
